Answer 1

You can use VisualTreeHelper.GetParent for Name1 and then its parent.

Or you can do it iteratively till you get an object of type TreeViewItem, this way you wont have to update your code when you change the xaml.

If you do it the 2nd way, it would look something like this:

DependencyObject parent = VisualTreeHelper.GetParent(Name1);
while(!(parent is TreeViewItem))
    parent = VisualTreeHelper.GetParent(parent);
TreeViewItem item = (TreeViewItem) parent;
